The final magic ingredient has been a willingness to risk it all. All in. No questions asked. The program started, and grew, from a determination to push the boundaries. Do the impossible. Climb the impassable--eat the inedible. Of course, there was often a safer, easier way down the waterfall or cliff face. But I rarely took it. That wasn't my aim. I wanted to show you how to survive when you have no safe options. And I loved it. I had learned a while back that whenever I had succeeded, it had always come about because of total commitment. Heart and soul. No holds barred. I realized, early on, that this would also be the key to this show. It's not rocket science. It's a lesson as old as the hills: Hold back from the tackle and that's when you get nailed. This commitment built the show. But I nearly paid for it with my life. Many times. There have been a multitude of near-death moments. None of which I am proud of. The list, though, is long. For old times' sake, I used to write them down. Then I gave up when I passed the fiftieth. Anyway, I don't like to think about those--they are in the past. Part of the learning process. Part of what made me stronger. Nowadays, the show is still crazy, but I manage the risk way better. I use ropes much more, off-camera. I think twice, not once, before I leap. I never did that before. It is called being aware. Aware of being a husband. Aware of being a dad. I am proud that I am learning; you only ever get it wrong once.
